Energy & Fuels, Год журнала: 2024, Номер 38(11), С. 9734 - 9741

Опубликована: Май 15, 2024

Natural gas hydrate is widely recognized as a promising energy source, with depressurization emerging the preferred method due to its simplicity and cost-effectiveness. Employing an appropriate strategy paramount for maximizing production efficiency, especially when faced constraints in reservoir heat supply. However, precise influence of rate on supply remains unclear. In this study, we employ fully coupled thermo-hydro-chemical (THC) model simulate 60 days dissociation using horizontal well under various schemes: decelerating (DD), regular (RD), accelerated (AD). We investigate effects dynamic changes production, multiphysics response Our findings indicate that most pronounced during initial stage. A positive correlation between observed. The amplitude fluctuations more significant at higher rates, these intensify increases. From perspective, sensible ratio increases rate. Gas primarily driven by flow dynamics propelled early stages constant pressure. Subsequently, it controlled ambient transfer. Therefore, additional replenishment can enhance improve economic viability not predominant. Such hold crucial reference value commercial exploitation resources.

CO₂/H₂ Separation by Synergistic Enhanced Hydrate Method with SDS and R134a

ACS Omega, Год журнала: 2024, Номер 9(28), С. 30234 - 30243

Опубликована: Июль 5, 2024

The synergistic effect of thermodynamic promoter tetrafluoroethane (R134a) and kinetic sodium dodecyl sulfate (SDS) can significantly improve the phase equilibrium conditions required for CO2 hydrate formation promote rapid generation hydrate. Based on this, this study investigates influence SDS R134a synergy separation CO2/H2 mixed gas using method. research reveals that without addition, forms first at gas–liquid interface before induction, hindering exchange. addition inhibit film, enhance initiator in process, accelerate nucleation hydrate, thus synergistically strengthen gases. Hydrate be achieved a concentration 100 ppm solution, growth becomes more significant with increasing concentration. Optimal efficiency maximum H2 are 500 SDS, 42.29 54.88% concentration, respectively. Decreasing initial charge temperature has little impact but reduces induction time, reducing it to 3 min 12 °C. This improved gas, providing better reference hydrogen purification by

Kinetic Properties and Dynamic Distribution of Hydrate Particles in a Water-Dominated System

Energy & Fuels, Год журнала: 2024, Номер 38(19), С. 18457 - 18468

Опубликована: Сен. 2, 2024

Hydrate agglomeration and blockage have emerged as significant challenges in deep-water oil gas exploitation. Currently, there are limited studies on the velocity distribution of hydrate particles inside pipe they move during flow process. This study utilizes computational fluid dynamics (CFD)–discrete element method (DEM) methods to simulate process slurry a horizontal pipe. The results indicate that at low rates, pressure drop is predominantly influenced by formation sedimentary moving beds. On other hand, high augmentation arises from dissipation energy caused frictional losses occurring between inner surface pipeline. A detailed analysis presented fluctuations affecting motion particles. illustrates particle lower region near wall enriched with particles, while uniformly distributed area center higher. obtained this provide comprehensive theoretical framework for further exploration into evolutionary patterns plugging.
